IOTA
Since Camel 2.23
Only producer is supported
According to IOTA Official site: "IOTA is the first open-source distributed ledger that is being built to power the future of the Internet of Things with feeless microtransactions and data integrity for machines."
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-iota</artifactId>
<version>x.y.z</version>
<!-- use the same version as your Camel core version -->
</dependency>
Options
The IOTA component supports 2 options, which are listed below.
Name | Description | Default | Type |
---|---|---|---|
lazyStartProducer (producer) |
Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. |
false |
boolean |
autowiredEnabled (advanced) |
Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. |
true |
boolean |
The IOTA endpoint is configured using URI syntax:
iota:name
with the following path and query parameters:
Query Parameters (7 parameters):
Name | Description | Default | Type |
---|---|---|---|
depth (producer) |
The depth determines how deep the tangle is analysed for getting Tips |

minWeightMagnitude (producer) |
The minWeightMagnitude is the minimum number of zeroes that a proof-of-work output/transaction hash must end with to be considered valid by full nodes |

Spring Boot Auto-Configuration
When using iota with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-iota-starter</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>
